Dashboard "ProxySQL Instance Summary" -> "Queries Execution Time" shows values for multiple proxysql instances even though only one instance is selected

Hi team,

Dashboard "ProxySQL Instance Summary" -> "Queries Execution Time" shows values for multiple proxysql instances even though only one instance is selected.

For each instance, there is a separate set of query types. In addition, it is also not clear which value belongs to which proxysql instance.

The query for dashboard "Queries Execution Time" doesn’t filter by node_name="$proxysql".

rate(proxysql_mysql_command_counter_latency_milliseconds_sum[$interval])

Thank you!
